Hi @Myron,
Western Digital has determined that some My Book Live devices are being compromised by malicious software. In some cases, this compromise has led to a factory reset that appears to erase all data on the device.
We understand that our customers’ data is very important. At this time, we recommend you disconnect your My Book Live from the Internet to protect your data on the device. Our engineering teams are actively investigating this issue. We apologize for any inconvenience this may have caused.
Please see the following article to learn more about disabling remote access to your My Book Live:
